Provençal Baked Fish with Roasted Potatoes & Mushrooms

Preheat oven to 425 degrees F.

Toss potatoes, mushrooms, 1 Tbsp. oil, salt, and pepper in a large bowl. Transfer to a 9x13-inch baking dish. Roast until the vegetables are just tender, 30 to 40 minutes.

Stir the vegetables, then stir in garlic. Place fish on top. Drizzle with lemon juice and the remaining 1 Tbsp. oil. Sprinkle with herbes de Provence. Bake until the fish is opaque in the center and flakes easily, 10 to 15 minutes. Garnish with thyme, if desired.
